Question 6
Examine the three base universal codon table below to answer this question.
The beginning part of the sequence of human insulin is Met-Ala-Leu-Trp. Which of the following sequences would be ideal for the production of human insulin in yeast?
- ATG GCT TTA TGG
- ATG GCG CTG TGG
- ATG GCC CTT TGG
Question 7
The following is a Codon Table from a hypothetical organism that lacks the DNA base G and uses only two bases for its codons. Which of the following DNA sequences would represent a synthetic gene for the protein Met-His-Pro-Tyr?
- AC CC CA TC
- CT AC CC CA
- CA CC AC CT AA
- AC CC CA TC AA
- AA CT AC CC CA
Question 8
The repressor in an expression plasmid is _______________________.
- the binding site for RNA polymerase
- none of the other selection
- the DNA sequence that controls the production of mRNA
- the sequence that directs the mRNA to the ribosome
Question 9
The DNA sequence of the expression plasmid adjacent to the ribosome binding site is:
—GGATCCATCTGCAGATCT—-
—CCTAGGTAGACGTCTAGA—-
It contains a BamH1 site (G^GATCC) and a BglII site (A^GATCT). In order for the synthetic gene to be inserted between these two sites, it should be constructed to have which restriction sites at its beginning and at its end? Select all that apply.
- EcoR1 (G^AATTC), followed by BamH1 (G^GATCC).
- BamH1 (G^AATTC), followed by EcoR1 (G^AATTC).
- BamH1 (G^GATCC), followed by BamH1 (G^GATCC).
- BamH1 (G^GATCC), followed by BglII (A^GATCT).
- BglII (A^GATCT), followed by BglII (A^GATCT).
Question 10
The following is the DNA sequence of the expression plasmid adjacent to the ribosome binding site:
-GAATTCGATATCAAGCTT
(EcoR1)(EcoRV) (HindIII)
You generated a synthetic gene for a human protein, but unfortunately you forgot to include the recognition sequences for EcoR1 at the beginning and for HindIII at the end of your synthetic gene, thus your gene looks like:
AGT——TAA
TCA——ATT
Given the following recognition sites: EcoR1 G^AATTC, EcoRV GAT^ATC, Hind III A^AGCTT, can you still insert your synthetic gene into the expression plasmid?
- No
- Yes
